Percutaneous Transhepatic Embolization for Isolated Pancreaticoduodenal Vein Rupture in Blunt Abdominal Trauma: A Case Report

Abstract

In blunt abdominal trauma, the prevalence of superior mesenteric vein injury or portal vein injury is low and surgical treatment is often difficult. We report a case of percutaneous transhepatic embolization in a patient who experienced isolated rupture of the pancreaticoduodenal vein (PDV). The patient sustained abdominal trauma in a motorcycle accident. A pseudoaneurysm was suspected in the anterior pancreatic head based on the portal venous phase of computed tomography. However, the lesion was not observed on celiac arteriography and superior mesenteric arteriography. PDV rupture was detected by additional percutaneous transhepatic superior mesenteric venography, and embolization was performed by trapping the PDV. This procedure is a safe, minimally invasive method that can be performed in patients with injuries of the portal venous system accompanying abdominal trauma; this procedure effectively reduces the need for invasive surgery.
